The same can be found in crustacean lineages, as branchiopods, ostracods, copepods, cirripeds
, and decapods that lost HcA and presented Hb for handling oxygen (Ter-williger and Ryan, 2001).
Pedunculate, Octolasmis, Cirripeds
, infestation, Portunus.
The remaining 5% of the zooplankton community was composed of cladocerans, ostracods, doliolids, polychaete larvae, medusae, fish eggs, ctenophores, salps, cephalopod paralarvae, bivalves, isopods, appendicularians, pyrosomes, mysiids, heteropods and echinoderms larvae, stomatopods and cirripeds
Epibionts includes bivalves, polychaete worms, ascidians, echinoderms, cirripeds
, bryozoans, cnidarians, sponges, and algae among other species.
The following taxa were considered as the key species (habitat-forming species) in the study area: Fucus vesiculosus, Furcellaria lumbricalis, Zostera marina, other higher plants (Stuckenia pectinata, Potamogeton spp., Ruppia sp., Zannichellia palustris, Myriophyllum spicatum, Ranunculus baudotii, etc.), charophytes, bivalves, and cirripeds
(Mytilus trossulus, Dreissena polymorpha, Macoma balthica, Mya arenaria, and Amphibalanus improvisus).
As part of the Bredin-Archbold-Smithsonian Biological Survey of Dominica, early investigations focused on the distribution of marine algae (Randolph & Rhine 1970), burrowing sponges (Rutzler 1971), balanomorph cirripeds
(Ross 1968), decapods (Kristeuer 1967, Raymond 1970) and echinoids (Porter 1966) from a few locations.
